FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 494,625, dated April 4, 1893. Application filed August 15, 1892. Serial No. 443.127. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JOHN H. CHAMBERLIN,

' a citizen'of the United States, residing at St.

Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Meeting-Rail Holders and Closers for Sashes, of which the following is a specification.

This invention relates to attachments to the meeting rails of that class of window sash employed in railway coaches wherein the u pper sash is stationary, and the meeting rails are without lips, for the purpose of retaining the meeting rails in close relations, and the invention consists in the construction and arrangement of parts, as hereinafter shown and described, and specifically pointed out in the claim.

In the drawings I have shown the invention applied to a railway coach window.

Figure l represents a View of a railway coach window from the inside of the car, and Fig. 2 a cross section on the line X X of Fig. l. Fig. 3 is an enlarged sectional detail of the meeting rails of a pair of sashes, showing my attachment arranged thereon. Figs. 4t and 5 are perspective views, from opposite sides, of one member of the attachment, and Figs. 6 and 7 are perspective views, from opposite sides, ofthe other member of the attachment.

A represents the lower or movable sash and A2 the upper or stationary sash, arranged in the ordinary manner in the casing and frame A3, as shown, the meeting rails having no lips, but with the adjacent surfaces parallel with each other and with the line of travel of the lower sash.

Attached to the meeting rail B of the sash A', is a plate D having a projecting head D2 provided with an inclined socket or cavity ct', while the other meeting rail B2 of the sash A2 is provided with a similar plate D3 having a projection D4 formed with an inclined face d2 corresponding to and adapted to enter the socket a when the sash A is closed, as in Figs. 1, 2 and 3. The plates D and D3 are secured to the meeting rails by being recessed into their adjacent surfaces, as the thinness of the railsin railway coach sash renders it necessary to thus secure them. The Vforms of the two plates are clearly shown in Figs. 4, 5, 6

and '7, and the manner of operation more clearly shown in Fig. 3. By this simple device the sashes when closed are drawn closely together, the reversed wedge form of parts d azinsurng the drawing of the meeting rails together and thus closing what has heretofore been an open joint. This space between the meeting rails of sashes has heretofore been a great source of annoyance in rail- 6o a2 will draw them closely together just the 7o same as if they were straight, so that a warped condition of the meeting rail or rails will not cause an open space to appeal-between them.

The rails and stiles of railway coach window sash are necessarily of thinner material than. ordinary sash, which precludes the possibility of employing the ordinary sash fasteners, but by the peculiar construction and method of fastening my attachment, itis perfectly adapted to the limited use to which it 8o is to be put.

I-.Iavlng thus describd lny invention, what I claim as new is- In a railway coach Window having the upper sash stationary and with the adjacent surfaces of the meeting rails parallel with the line of travel 0f the sash, of a plate D3 recessed into the inner face of the meeting rail of the upper stationary sash, and provided with an inclined head a2, and a plate D re- 9o cessed into the outer face of the meeting rails of the movable sash and provided with an inclined socket a adapted to fit over said inclined head when said movable sash is closed,

substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand 1n the presence of two subscribing witnesses.
